Question

Immunoglobulins (antibodies) are basically
A. Lipoproteins
B. Phospholipids
C. Glycoproteins
D. Nucleoproteins

Answer 1

Hint: Antibodies can happen in two physical aspects, a soluble structure that is emitted from the cell to be free in the blood plasma, and a membrane-bound aspect that is connected to the ground of a B cell and is pertained to as the B-cell receptor (BCR).

Complete Answer:
Let us analyse the given options to find out the correct answer.
Option A: A lipoprotein is a biochemical convention whose major objective is to transfer hydrophobic lipid (also known as fat) molecules in liquid, as in blood plasma or other extracellular liquids. This is an incorrect option.

Option B: Phospholipids (PL) are a grade of lipids whose members have a hydrophilic "head" including a phosphate fraction, and two hydrophobic "tails" arose from fatty acids, enlisted by alcohol debris. The phosphate group can be amended with reasonable organic molecules such as choline, ethanol-amine or serine. This is an incorrect option.

Option C: Immunoglobulins, also understood as antibodies, are glycoprotein molecules generated by plasma cells (white blood cells). They act as a significant part of the immune reaction by mainly comprehending and compelling to special antigens, such as bacteria or germs, and benefiting in their devastation. This is the correct option.

Option D: Nucleoproteins are proteins that are structurally correlated with nucleic acids, either RNA or DNA. Particular nucleoproteins comprise ribosomes, and viral nucleocapsid proteins. This is the incorrect option.

Thus, option C is the correct answer.

Note: An antibody is also understood as an immunoglobulin is a huge, Y-shaped protein generated primarily by plasma tissues that is utilized by the immune network to equalize pathogens such as viruses and bacteria. The antibody comprehends an unusual molecule of the pathogen, named an antigen, via the speck antigen-binding inconsistent area.
